SERVICE_FAILURE_ACTIONS

The SERVICE_FAILURE_ACTIONS structure represents the action the service controller should take on each failure of a service. A service is considered failed when it terminates without reporting a status of SERVICE_STOPPED to the service controller.

typedef struct _SERVICE_FAILURE_ACTIONS {
  DWORD dwResetPeriod;
  LPTSTR lpRebootMsg;
  LPTSTR lpCommand;
  DWORD cActions;
  SC_ACTION* lpsaActions;
} SERVICE_FAILURE_ACTIONS, 
*LPSERVICE_FAILURE_ACTIONS;

Members

dwResetPeriod

Time after which to reset the failure count to zero if there are no failures, in seconds. Specify INFINITE to indicate that this value should never be reset.

lpRebootMsg

Message to broadcast to server users before rebooting in response to the SC_ACTION_REBOOT service controller action.

If this value is NULL, the reboot message is unchanged. If the value is an empty string (""), the reboot message is deleted and no message is broadcast.

lpCommand

Command line of the process for the CreateProcess function to execute in response to the SC_ACTION_RUN_COMMAND service controller action. This process runs under the same account as the service.

If this value is NULL, the command is unchanged. If the value is an empty string (""), the command is deleted and no program is run when the service fails.

cActions

Number of elements in the lpsaActions array.

If this value is 0, but lpsaActions is not NULL, the reset period and array of failure actions are deleted.

lpsaActions

Pointer to an array of SC_ACTION structures.

If this value is NULL, the cActions and dwResetPeriod members are ignored.

Remarks

The service control manager counts the number of times each service has failed since the system booted. The count is reset to 0 if the service has not failed for dwResetPeriod seconds. When the service fails for the Nth time, the service controller performs the action specified in element [N-1] of the lpsaActions array. If N is greater than cActions, the service controller repeats the last action in the array.
